Patent DE-3934024-A1 (DE)
Title: Reproducible mixt. syringe - with magnetic stirrer driven by motorised magnet inside hollow piston
Inventor: WILDANGER HANS-JOERG
IPC: G01N35/00
Filed: 1989-10-12
Abstract: A precisely reproducible admixture of liq. to a liq. sample, which can be chosen within wide limits, specially for an automatic quantitative analysis, is effect by a stirrer, which is integrated in the interior of a syringe. The successive volumes, defined by the sequence of strokes of the syringe piston, are thereby thoroughly mixed. The cylinder(1) of a syringe includes a stirrer(3) apart from the piston(2). The shape of the stirrer is such that with the piston IN, the syringe is almost filled up but that the stirrer is still easy to turn. The stirrer encloses a cylindrical permanent magnet(4). The hollow piston(2) has on the shaft of an electric motor(5) another permanent magnet(6). A positioning drive(7) is used for a sensitive positioning of the piston. A hose(8) joins the syringe to a multi-way valve(9) with a drive, inlets(10,11) and outlet(10) hoses. ADVANTAGE - This saves all hoses, requires no other vessels to prepare, rinse or dry and speeds up the mixing process.

Title: Waste combustion with pure oxygen, melting mineral component - gives redn. of waste gas vol., facilitating sepn. of impurities
IPC: F23L7/00
Filed: 1990-08-18
Abstract: Thermal treatment of waste and residues is carried out by combustion, using undiluted pure O2 as oxidant. Combustion is pref. carried out so that the mineral constituents melt, pref. by keeping the temp. above the m.pt. of these. The O2 may be diluted by mixing with pt. of the waste gas or with N2, water, steam and/or CO2. Additives, pref. fly ash or slag from waste combustion and/or reaction prods. from waste gas purificn., may be used which melt at a temp. below the m.pt. of the minerals or in the same temp. range. The waste pref. is mixed with carbonaceous material (I), pref. coal, coke, pyrolysis residues, spent coke from waste gas purificn. plants, bitumen, tar, oil and/or wood, which is burnt with undiluted O2, so that the minerals melt. The waste and (I) pref. are mixed and pulverised to dust before combustion in a suitable smelter. USE/ADVANTAGE - The use of pure O2 reduces the volume of waste gas formed in the combustion of 1 t household waste from ca. 6000 cu.m to 1800 cu.m, i.e. 30% of the usual amt. Reducing the vol. increases the concn. of impurities, which facilitates sepn. and (extensive) elimination of the emission of harmful organic matter, esp, dioxins, chlorinated phenols, hexachlorobenzene, polyaromatic cpds. and incompletely burnt impurities. In an example, a mixt. of 1 kg dry residue (slag, fly ash and reaction prods. from waste gas purificn.) and 100 g mineral coal was pulverised finely and burnt in a smelter in an O2 atmos. The residue melted at 1600 deg.C, forming a glass, which set to a prod. resistant to leaching on cooling. 0.22 cu.m waste gas, mainly CO2, were formed.
Patent DE-4026905-A1 (DE)
Inventor: HEUMANN ANTON
IPC: F04D29/22
Filed: 1990-08-25
Abstract: The invention concerns a device for fully compensating the axial thrust in centrifugal pumps with a first device which brings about a hydraulic compensation of the axial thrust with the aid of a pressure difference generated by the impeller of the centrifugal pump and a second device which takes up the remaining axial thrust when the pressure head is inadequate for the operation of the first device. In order also to overcome the overload region which can be a problem in axial thrust compensation without using an additional back-up bearing, the invention provides for a second compensating device, also hydraulic, which brings about an increase in pressure in the pressure side of the lateral impeller space when the pressure head falls below a predetermined value, by which this device assumes the compensation of the axial thrust at a time when axial thrust compensation dependent on the pressure differences between the impeller intake and discharge can no longer act satisfactory.

Patent DE-4033443-A1 (DE)
Inventor: NEUMANN ULRICH
IPC: B29C48/90
Filed: 1990-10-20
Abstract: The invention relates to an installation for the extrusion of plastic tubes having a wall-thickness measuring device 6, which is arranged between a calibrating sleeve directly downstream of the extruder 1 and a run-through cooling chamber 4 in a chamber 11. The chamber 11 is under negative pressure and is connected on the outside tightly against the calibrating sleeve 5, which is cooled with cooling water and uses negative pressure to draw the tube 3 to be calibrated against the wall inner side. In the calibrating sleeve 5, the tube is only cooled to such an extent that it is just dimensionally stable. Therefore, the distance of the calibrating sleeve of the directly downstream wall-thickness measuring device 6 from the extruder can be kept comparatively short. Due to the cooling of the tube in the calibrating sleeve 5 and the small distance of the wall-thickness measuring device 6 from the extruder, not only are measuring errors caused by uneven cooling eliminated, but also the dead times for the automatic control are kept short. <IMAGE>
